I would try that. You don't have anything to lose but time by trying
it. I've never seen it on Pulmonaria either.

I've never had a Pulmonaria get powdery mildew b4, but this one seems
to have it bad. I see new clean leaves coming out. Would it be ok to
just remove all the old leaves rather than mess around w sprays and
such that would only provide minimal success and still allow the
fungal problem to hang around?
